4- Claims. 1

My present invention relates to pumps, and more particularly to a bilge pump adapted to be installed in the deck of a boat with the upper surface. of the pump cover lying flush with the deck.

The general object of my invention is to provide a simple, compact, and reliable pump, easy to install and repair and which will replace thepresent deck pump which is usually mounted on top of the deck, or on a floor, and hence constitutes 'an obstacle over which to stumble as.

well as being exposed. to freezing in sub-zero weather.

Gther objects and novel features of the construction and arrangement of parts comprising my improved pump will appear as the description of the invention progresses.

Inthe accompanying drawings illustrating a preferred embodiment of my invention:

Figure 1 is a sectional plan view taken on the line 2-4 of Fig. 3, and looking in the direction of the arrows.

My novel pump is characterized in the following respects: By being housed in the decki'rather than above deck, the entire deck space is available and a hazard to traflic eliminated. Dan

where beams or the like would ordinarily in-- terfere with the piping. The pump cover acts as a rocker arm-for operating the pump piston and is thus a part of the operating mechanism of the pump which will never be omitted or forgotten. When the pump is not in use and the operating handle removed, the cover is left in' place flush with the deck, and hence will automatically drain itself. Moreover, the cover, the link which connects the cover to the piston, and

.the piston itself may all be removed as a unit without. removing any bolts,inuts or pins. .Tlihis eliminates the need for tools when priming, draining or cleaning the several valves of the pump. The drain valve is automatic and can be easily removed when not needed. It drains both the suction and the discharge chambers, which is an advantage when the pump is used in freezing weather. Also the piston and the discharge'port outlet are so designed as to provide a longer'guidc and a better seal for the piston. Other advantages will appear from the following detailed description of the'construction and operation of my pump.

Referring to the drawings, it designates the deck of the boat, or the floor of a loft or other structure, provided with an orifice Ii through which extends a pump body i2 having attached thereto or formed integral therewith an annular plate i3, the upper surface of which lies flush with the deck it. Associated with the an nular plate !3 is a pivoted cover plate M, which, when closed, lies flush with the annular plate I 3 and deck iii;

The cover plate Hi is pivotally mounted on a lugs 1 6 on the under face of the armu-lar plate It a The spaced ears or lugs iii are provided with slots through which may pass the non-cylindrical ends of the shaft 15. With this construction, the cover plate M may be inserted in position in the spaced ears or lugs IE or removed therefrom at will, without the necessity of removing bolts, nuts, or other fastening means.

Further, all parts attached to the under face 'ofthe cover plate I 4, as hereinafter described,

may be removed as a unit for inspection, repair or cleaning.

On the under face of the cover 14 is a rib i1 having a socket 18 formed therein and with the upper end thereof terminating in a slot (not shown) in the cover plate 14. The socket [8 receives a handle i'Sa by means of which the cover plate l4 may be oscillated between the full line position, and the dot and dash line position shown in Fig. 1 to operate the pump piston.

Formed within the pump body it! is a cylinder 59 having its bottom 20 spaced apart from the bottom of the'body as shown, A vertical web 2| extends across the pump body l2 between the bottom 28 of the cylinder I9 and the bottom of the pump body i2, (see Fig. 1) thus dividing the pump body into'two chambers, an intake chamber 22 and a discharge chamber 23.

Connecting with the intake chamber 22 is an intake port 24 havingapipe 24'a connected thereto and leading to the bilge of the boat. Connecting to the discharge chamber 23 is a discharge port 25 having a pipe 2511 connected thereto and leading outward through the side of the boat at a point above the water line.

In the bottom 23 of cylinder [9 and within the confines of the intake chamber 22 are intake ports 26 provided with an intake valve leather 2? having secured thereto a valve weight 28, the valve leather being secured to the bottom 26 by the bolts 29 and clamps 29a. Also, for one of the bolts 29 there has been substituted a discharge valve stop stud 5| (see Fig. 3) and which is in alignment with one of the piston intake valve leathers 39. The function of the discharge valve stop stud 5| is to engage with the valve leather 39 to open the piston intake ports 38 and permit water to pass above the piston head and into the outlet chamber 23.

In the bottom 20,'within the confines of the discharge chamber 23, is the discharge chamber valve comprising a drain cage 30 screwed into the bottom 29, said cage having a valve seat 3|, and a plurality of drain passages 32a extending from the seat 3| into the chamber 23. Slidably mounted in the cage 38 is a sliding valve 32 on the stem of which is mounted and secured by nut 33 a coil spring 34 which constantly urges the valve 32 into closing engagement with the valve seat 3|.

Mounted within the cylinder ii) for reciprocating movement therein by cover it and its handle is a piston 35, the skirt 35 of which is provided at one side with an open port 31 (see Fig. 1). The head of the piston 55 is provided with a plurality oi piston intake ports 38 normally closed by the piston valve leather 39, such leather being weighted by valve weights 40 held on the leather by the rivets ii. The members 39, 4G and M are secured to the head of the piston 35 by a connecting link bracket 42 and bolts 43. Pivotally connected to a bearing pin 44 rotatably mounted in the central upper end of the connecting bracket 42 are the lower ends of the connecting links 65, the upper ends of which are pivotally mounted on a bearing pin 48 which is rotatably mounted in the rib I! on the under face of the cover plate It.

With the device constructed and arranged as above described, the normal or inoperative position of the parts relative to each other is as shown in full lines. The intake pipe 24a leads to the bilge of the boat in which the device is installed. The discharge pipe 25a leads out through the side of the boat at a point above the waterline. The intake port valve leather 21 closes the intake ports 26. The discharge valve 32 is held open by the piston. The piston 35 is in its lowermost position with its valve leathers 39 closing the piston intake ports 38.

The operator places the lever 18a in the socket l8 and swings the upper end thereof to the left, as viewed in Fig. 1, and as shown in bro-ken lines, thereby swinging the cover plate M in an arc about the shaft l5, and, by means of the connect-- ing links 45, drawing the piston 35 upwardly in the cylinder l9 to the dot and dash line position shown in Fig. 1.

Immediately upon the start of this upward movement of the piston 35, the valve 32 seats on the valve seat 3|, thus closing the chamber between the piston and the cylinder head; the intake valve leather 21 opens the inlet ports 25 and suction is created in the intake pipe 24a, thereby drawing the water upward through the pipe 24a and filling not only the intake chamber 22 but allowing the water to flow upwardly through the inlet ports 26 and into the chamber between the piston and cylinder head. Should the pump require priming, this may be easily done by pouring water into the upper end of the piston 35.

The handle 18a having reached the dot and dash line position is now moved back to its starting position, as shown in full lines in Fig. 1. During this movement the valve leather 2'! seats on the intake ports 26, while the valve leathers 39 lift away from the piston intake ports 38 in the cylinder head, forcing the water upwardly and into the piston 35. As the piston moves upwardly, the water within such piston flows through the discharge port 3'! of the piston into the discharge chamber 23, and from thence through the discharge pipe 250, outward through the side of the boat.

After the pumping operations have been completed, the operator moves the handle I811 to the full line position shown in Fig. 1, bringing the piston head into engagement with the discharge valve 32, thus depressing the valve and permitting the water in the chamber between the piston and cylinder to flow downwardly into the discharge pipe 25a, and simultaneousl opening one of the ports 38 to permit water in the body of the piston 35 to flow downwardl and through the valve 32 into the discharge pipe 25a.

The pumping operation having been completed and the pump drained, the operator removes the handle lBa from the socket l8.

It will be noted that all parts of my pump are readily accessible without the necessity of removing any bolts, nuts, or pins; that the pump is made with a minimum number of parts; and that these parts are so designed and arranged as not to corrode or depreciate through long disuse. My pump is self-draining, and easy to prime. It displaces the maximum amount of water with the minimum of effort, and is so designed as to give long reliable service.

It is flush with the deck and is protected from freezing, by being housed from the weather. It adds measurably to the safety of all on board the boat, as it cannot be stumbled over, is not injured by seas coming over the deck, and is always ready for instant use.

Further, if it is desired to remove the piston or other parts of the pump connected to the cover plate i4, thismay be accomplished by merely swinging such cover plate It upwardly and to the left, as viewed in Fig. 1, until the non-cylindr'tcal ends of the shaft l5 come into registry with the slots in the ears or lugs 18, whereupon the cover plate It, links 15, piston :35, and all parts attached thereto may be lifted from the pump as a unit.

Obviously various changes in the size, shape and arrangement of parts may be made by those skilled in the art, and I am therefore not to be limited to the exact construction shown and described other than as required by the appended claims.
